The model RF-460 is a small Reflow Soldering Machine corresponding to lead-free soldering and using
infrared radiation and nitrogen (N2) for the basic heating. While this is a small table-top reflow machine, it a
method with six far infrared (IR) zones, and the precise and stable temperature profile required for lead-free
reflow soldering can be obtained. By use of far infrared radiation and nitrogen (N2), the various requirements
for lead-free soldering can be met sufficiently. A max. temperature of 350°C and solder wettability are realized.


  • This is a table-top reflow soldering machine with correspondence to nitrogen (N2). Circuit boards up to 300×300mmcan be processed.
  • 􀀍Rapid heating is performed with a 6-zone quartz heater using far infrared radiation and nitrogen (N2), and thedesired temperature profile can be obtained.
  • 􀀍Precise temperature control (±0.3%) up to max. 350°C and stable temperature profiles can be obtained with a highprecisionPID temperature controller.
